@Cd-MaN Yep, like I wrote, it impacts the digital signature. However, most programs will run fine with an invalid digital signature. Windows doesn’t care, unless a special flag is set which I’ll blog about later.

@anonymous I’m using SetProcessDEPPolicy in my dll SetPermanentDEP, to be featured in an upcoming blogpost.
And if you’re refering to XP SP2, then it’s not that DEP is disabled, but limited to the system and other Microsoft programs.
